Я реализовал 2FA в своем приложении Django, однако я получаю AttributeError at /signup/ 'User' object has no attribute 'profile' ошибку при нажатии кнопки «Отправить» в своей форме регистрации. Это показывает мне, что в six.text_type(user.profile.email_confirmed) строке возникает ошибка.

У меня нет никакой пользовательской модели пользователя. Я использую модель пользователя по умолчанию.

Не могли бы вы, пожалуйста, рассказать мне, в чем проблема и как ее исправить?
